Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.

Summary:
- Clean up a TODO about permanent failures.
- Clean up a TODO about failing tasks after too many retries.
- Clean up a TODO about testing for bad leases.
- Make the lease/retry implementation more flexible and natural.
- Make completely bogus tasks fail permanently.
- Make PhabricatorMetaMTAWorker use new `getWaitBeforeRetry()` (as intended), not hackily implement logic in `getRequiredLeaseTime()`.
- Document worker hooks for failures and retries.
- Provide coverage on everything.
Test Plan: Ran unit tests. Ran `bin/phd debug taskmaster`.
